Title: Method and device for winding magnetic recording head coil
Inventor: NAKABAYASHI MASAKI
IPC: G11B5/17
Filed: 1984-02-14
Abstract: PURPOSE:To attain the automatic winding of a coil round the core part of a magnetic recording head by means of a machine which is so far impossible, by connecting a steel wire of the prescribed length to the tip part of a magnetic recording head coil and winding the steel wire round a circumference circuit by the induction due to the magnetic force. CONSTITUTION:A magnetic steel wire 8 of an extremely small thickness is connected to the tip of a coil 4 which is wound round the core part of a magnetic recording head. When the wire 8 is fed out of a coil supply part 15 and put on a track K, the coil 4 is sucked by the magnetic force of a wound magnet 9. Then the coil 4 moves on a base plate along the track K. The wire 8 is pierced through a gap part 5 of the head 1 which is inserted within a groove part 13 so that the track K passes through the part 5. Therefore the coil 4 led by the wire 8 also passes through the part 5. The wire 8 enters a rectilinear part Ks after passing through a curve part Kr and then goes into the original groove part 13 again via the part Kr. When the wire 8 passes throught the part 5 again, the coil 4 is wound round a core part 3 of the coil 4 by a round.

Title: Electromagnetic suspension system
Inventor: SASAKI MITSUO
IPC: B60G17/015
Filed: 1991-02-19
Abstract: PURPOSE:To keep a magnetic flux density constant by forming a distance between magnetic path ends of a clearance part so as to be the narrower in a short part, the wider in a long part of the full length in response to the total length of this magnetic path, and correcting a variation in the magnetic flux density with that of the magnetic flux density by means of the relative length of a clearance. CONSTITUTION:An opposed surface between an upper outer side permanent magnet 1j and an upper inner side permanent magnet 1m and another opposed surface between a lower outer side permanent magnet 1k and a lower inner side permanent magnet 1n, constituting both ends of a clearance part 1c of a magnetic path A, are formed into a taper form so as to make their clearance wider in proportion as getting nearer to the center. Since the magnetic path A is made up into a ring form, length of this magnetic path A differs at the inside and the outside respectively, so that it is the lower, in magnetic density, the longer at the outside part where a distance becomes lengthened, thus strength in both magnetic fields B1 and B2 varies at each spot. As the magnetic path end is made up into a taper form, however, any drop in the magnetic flux density due to a difference in the length of the magnetic path A is offset by that of the magnetic flux density in the clearance part 1c, through which the magnetic flux density of the whole clearance part 1c becomes uniformized, thus these magnetic fields B1, B2 of constant strength are securable in this way.
